Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620266, here are decompositions:

3 + 31620263 = 31620266
37 + 31620229 = 31620266
43 + 31620223 = 31620266
127 + 31620139 = 31620266
157 + 31620109 = 31620266
199 + 31620067 = 31620266
229 + 31620037 = 31620266
277 + 31619989 = 31620266

Showing the first eight; more decompositions exist.
